[XFRM]: RFC4303 compliant auditing
This patch adds a number of new IPsec audit events to meet the auditing
requirements of RFC4303. This includes audit hooks for the following events:
* Could not find a valid SA [sections 2.1, 3.4.2]
. xfrm_audit_state_notfound()
. xfrm_audit_state_notfound_simple()
* Sequence number overflow [section 3.3.3]
. xfrm_audit_state_replay_overflow()
* Replayed packet [section 3.4.3]
. xfrm_audit_state_replay()
* Integrity check failure [sections 3.4.4.1, 3.4.4.2]
. xfrm_audit_state_icvfail()
While RFC4304 deals only with ESP most of the changes in this patch apply to
IPsec in general, i.e. both AH and ESP. The one case, integrity check
failure, where ESP specific code had to be modified the same was done to the
AH code for the sake of consistency.
